I have kernel version 4.1.10-bone16 with the same issue as pbft. I tried following the “Compatibility issues section”.
I did the following and rebooted:
When I load BB-UART5 and check dmesg I get the following:
I also tried adding the line “Disable: HDMI” to uEnv.txt, but didn’t change the behavior.
What am I missing here? My final objective is actually to disable the HDMI to use the pins for the PRU.
Thank you very much for the help! It is quite impressive that almost every post I see about beaglebone I see the name Robert Nelson.
Thank you very much for the response!
The problem is solved now. I am going to post here to help whoever might have a similar issue.
My situation was that I had a flasher image with an old 3.8.13 kernel.
Then I would update the kernel to a version 4.1.x. It seems like a big leap like that might give problems, because it was ignoring my changes to uEnv.txt.
The solution was to get the jessie version from http://beagleboard.org/latest-images and flash my beagle with it.
Then you can change to a 4.1x kernel of choice if you want and when you change uEnv.txt file, it will be applied on reboot.
